Abstract
A process for producing modified rubber moulding materials, a first mixture (A) that contains at least one alkyl acrylate or methacrylate (a) having the general formula (I), in which R<1> stands for a hydrogen atom or a methyl group and R<2> stands for an alkyl group with 1 to 32 carbon atoms, a first monomer (b) with two or more double bonds and optionally a second or several other monomers (c), is in a first step polymerised into a rubber (B), preferably together with free radicals. In a second step, the thus obtained rubber (B) is dissolved into or swollen with a third or several other monomers (d), optionally with admixture of a solvent, and in a third step, the second mixture (C) obtained by dissolving or swelling is polymerised into the modified rubber moulding material (D).
Description
The present invention relates to prepare the method and the modified rubber moulding prepared by this method of modified rubber moulding, the especially vinyl cyanide/phenylethylene ethylene/propenoic acid ester moulding material that is in dissolving or solvent swelling state.
Modified rubber moulding is that wherein elastomerics (as rubber) microcell is imbedded material in the thermoplastic material matrix.At present the demand to modified rubber moulding with surface luster, shock strength and tensile strength is quite big.Required mechanical property just is being based on this specific domain structure.
The heterogeneous characteristic of modified rubber moulding and consequent domain structure based on the fact be that this material comprises mutually non-miscible or only partially miscible different polymeric constituents.The shock strength of material comes from the energy absorption that increases in being deformed into breaking-down process.The energy that consumes is used to form microcavities or is used to cause the sliding process of matrix polymer chain.Therefore heterogeneous characteristic is the necessary condition that obtains high impact.
Following characteristics also are favourable:
1. two kinds of chemically different polymeric constituents form the stabilising dispersions that limits particle size, and this dispersion did not both occur being separated in thermoplastic melt (processing), at high temperature formed again and did not trend towards homogenizing in the macromolecular solution.
2. between elastomer particles and matrix, must there be coupling, promptly must can transmits stress on the phase border.
The most effective phase coupling at the elastomer particles boundary realizes by graft copolymerization.For example, in preparation vinyl cyanide/phenylethylene ethylene/propenoic acid ester (ASA) moulding material, the method of generally taking is at first to form acrylic elastomer, then by with the polymerization of mixtures that comprises vinylbenzene and vinyl cyanide, will be to acrylic elastomer based on back two kinds of monomeric copolymer grafted.
The method of emulsion polymerization prepared ASA moulding material is disclosed among (for example) DE3206136,3149046,3149358,3227555,3129378,3129472,2940804,2826925 and 1911882.This rubber in emulsion by n-butyl acrylate with contain the monomer preparation of two two keys on a small quantity.The shortcoming of this method is that owing to letex polymerization and because the polymeric dispersions precipitation has generated a large amount of water, it must be removed.In addition, the moulding material by this method preparation does not have enough shock strengths and tensile strength for all purposes.The gloss of while by the molding of its production can not change in wide region.
Owing to these reasons, the preparation moulding material is best in solution, and these methods are disclosed among EP0095919 and the DE1182811.
According to EP0095919, the grafting of comonomer does not take place on rubber, promptly there is not effective coupling at boundary.According to DE1182811, but rubber is by the comonomer preparation of the two keys with two radical polymerizations of n-butyl acrylate and 0.5 to 10wt%.The rubber transformation efficiency that is aggregated in of styrene/acrylonitrile (SAN) monomer mixture is to begin in 10 to 80% o'clock.As a result, the grafting of rubber part is different with the composition of polymeric matrix, causes the relatively poor mechanical property of moulding material.Simultaneously, the polymerization of rubber unit in graft shell (being grafted branches) causes the vicat softening temperature of product to reduce.
The object of the invention is to provide a kind of preparation method with modified rubber moulding of improved shock strength, tensile strength and extension at break.
We find that the object of the invention passes through this novel method and realize, wherein in the fs, to contain the acrylic or methacrylic acid alkyl ester (a) of at least a general formula (I), the first kind of monomer (b) with two or more pairs of keys and (if needs) second kind of monomer (c) or multiple monomeric first kind of mixture (A) and preferably carry out radical polymerization obtain rubber (B) in solution, described general formula (I) is:
R wherein
1Be hydrogen or methyl, R
2Be the alkyl of 1 to 32 carbon atom,
In subordinate phase, gained rubber (B) adding or not being dissolve or swell in the third monomer (d) or the multiple monomer under the solubilizing agent situation, is formed second kind of mixture (C), and
In the phase III, the second kind of mixture (C) that forms after dissolving or the swelling preferably carried out radical polymerization obtain modified rubber moulding (D).
Graft copolymerization was carried out in the phase III, and the skeleton of gained graft copolymer is formed by rubber (B) and these grafted chains are formed by the third monomer (d).Owing to can not carry out 100% grafting, so some rubber keep not grafting and form the chain polymerization thing simultaneously by the third monomer (d), therefore have three types molecule in moulding material.
Preparing improved modified rubber moulding by the inventive method can followingly carry out, promptly the fs with acrylate or methacrylic ester and a kind of monomer copolymerization with two or more pairs of keys.We suppose now, and the improvement of moulding material performance is particularly based on the following fact:
1. two keys of residual first kind of monomer (b) are used as the grafting site of the growing chain of the third monomer (d) after the fs copolymerization,
2. the molecular weight that contains the polyacrylic acid of first kind of monomer (b) of introducing or alkyl methacrylate is introduced comparing of first kind of monomer (b) and is not improved with not having,
3. use first kind of monomer (b) to reduce the low molecular weight part of rubber with two or more pairs of keys.This causes having improved its mechanical property.

2) length) and the mixture adjustment.This adjusting second-order transition temperature based on the fact be that the second-order transition temperature of acrylate and methacrylic ester begins to reduce with the side chain lengths increase, pass through minimum value then, increase once more at last.When minimum value appears at the side chain of about 7 carbon atoms (for polyacrylic ester) and when the side chain of 10 carbon atoms (for polymethacrylate).Therefore, this side chain R
